Abstract
The invention provides a forging method for a variable-speed bearing inner ring of a seeder. The forging method comprises the following steps: (1) heating a metal mould of the bearing inner ring to a temperature being 1250 DEG C by a resistance heater, wherein the metal mould is electrically connected to a temperature sensor and a single chip microcomputer; and controlling the resistance heater according to a signal of the temperature sensor by the single chip microcomputer, and enabling the metal mould to be in a 1260-DEGC constant-temperature state; (2) putting blank into a heating furnace to heat, monitoring a temperature of the blank in real time, pouring blank molten steel into the metal mould when the temperature of the blank reaches 1250 DEG C, and controlling the resistance heater to stop heating the metal mould by the single chip microcomputer while pouring the blank molten steel into the metal mould; and (3) cooling the blank to a temperature being 850 DEG C, and then, taking out a bearing inner ring casting from the metal mould. According to the forging method, a conventional blank preparation method is changed, and efficiency is improved; and meanwhile, with the adoption of the single chip microcomputer, control is accurate, so that efficiency is improved and cost is reduced.
Description
Technical field
The present invention relates to technical field of forging, the forging side of a kind of seeder variable-speed bearing inner ring
Method.
Background technology
Along with the development of farm-machinery industry, various metals are widely used in various field, the forging work of metal
Industry is various, affects the character of metal very big on different forging temperatures in metal forging, and in metal, adding ingredient is not
With, ratio difference all can cause the change of the pouring temperature in forging process and forging temperature.
Summary of the invention
In order to overcome the deficiency in background technology, the invention discloses the forging side of a kind of seeder variable-speed bearing inner ring
Method.
The technical scheme is that the forging method of a kind of seeder variable-speed bearing inner ring, comprise the following steps:
(1) use resistance heater that the metal die of bearing inner race is heated to 1250 ° of C, metal die electrically connects temperature and passes
Sensor and single-chip microcomputer, described single-chip microcomputer is according to temperature sensor signal, by controlling input voltage and the electric current of resistance heater,
Controlling resistance heater makes metal die be in the temperature constant state of 1260 ° of C；
(2) stock is put into heating furnace to heat, and use infrared radiation thermometer that the temperature of stock is monitored in real time, when
When the temperature of stock reaches 1250 ° of C, stock steel juice is poured in metal die, and stock steel juice is being poured into metal pattern
While in tool, Single-chip Controlling resistance heater stops heating metal die；
(3) after then stock being cooled to 850 ° of C, bearing inner race foundry goods is removed from metal die.
Beneficial effects of the present invention: the present invention changes traditional embryo method processed, improves efficiency, meanwhile, uses monolithic
Machine precise control is errorless, improves efficiency, reduces cost.
Detailed description of the invention
The embodiment provided the present invention in conjunction with specific embodiments is described in further detail:
The forging method of a kind of seeder variable-speed bearing inner ring, comprises the following steps:

Sensor and single-chip microcomputer, described single-chip microcomputer is according to temperature sensor signal, by controlling input voltage and the electric current of resistance heater,
Controlling resistance heater makes metal die be in the temperature constant state of 1260 ° of C；
(2) stock is put into heating furnace to heat, and use infrared radiation thermometer that the temperature of stock is monitored in real time, when
When the temperature of stock reaches 1250 ° of C, stock steel juice is poured in metal die, and stock steel juice is being poured into metal pattern
While in tool, Single-chip Controlling resistance heater stops heating metal die；
(3) after then stock being cooled to 850 ° of C, bearing inner race foundry goods is removed from metal die.
In this description, the present invention is described with reference to its specific embodiment.But it is clear that still can make various
Amendment and conversion are without departing from the spirit and scope of the present invention.Therefore, description is considered as illustrative and non-limiting
's.
